Application filed January 21, 1921. Serial No. 438,838.

To all 'who/ml t may concern Be it known that I,WILLIAM I-I. EDWARDS,-

a citizen of the United States, residing at Grand Rapids, in the county of Kent and State of Michigan,.have invented new and useful Improvements in Coverings for Books, of which the following is a specilication. l

The present invention relates to coverings for books, particularly for loose-leaf binders, and its object is to provide such apcovering which may be readily adjusted to such books or-binders of different thicknesses.

This and any other objects appearing hereinafter are attainedby, and the invenbinder, certain parts being broken away;

Fig..2 is a sectional view of said looseleaf binder taken on planes corresponding to line'2-2 of Fig. 1, the parts broken away in Fig. 1 however being shown in Fig. 2;

Fig. 3 vis a sectional view of the same taken on a plane corresponding to line 3--3 of Fig. 1; and v Y Fig. 4 is a sectional view of said loose-leaf binder taken on a plane corresponding to line 4 4 of'Fig. 1; Y

In the embodiment of the invention chosen forV illustration by the drawings and for detailed description in the bodyr of this specication,my lcovering is shown applied to a book known as aloose-leaf post binder, in which the loose leaves 1 are held in place by posts 2 extending through orifices 3 in the leaves binding portions, such posts being carried by the binding portion 4 of one cover-the back cover 5--and extending through the binding portion 6 ofthe other cover-the front cover 7. The body portions 8 of these covers 5 and 7 are joined to their said binding portions 4 and 6 by their Yflexible intermediate portions 9 respectively.

My covering comprises a pair of sheaths, for the covers 5, 7 respectively, into Vone of which sheaths y10 the outer edge 11 of the front cover 7 is thrust, and into the other sheath 12 the outer edge 13 of the back cover 5V is thrust in like manner. One sheath, as 10, has a flexible sheet 14, forming i a back for the book or binder, and extending from said sheaths outer wall 15 around the binding edge of the leaves 1 and into the sheath 12, passing between its outer wall 16 and the cover 5 of the binder or book therein.` The free end of this sheet has a strap portion 17 which extends around the outer edge 13 of said cover 5 and thence through an opening 18 in theinner wall 19 of said sheath 12.

It lwill be seen that the free end of this strap 17 Vmay be drawn by hand to cause both covers 5, 7 tobe seated inthe bottoms of their respective sheaths 1Q, 12 and to tighten the sheet 14 on the edges 20 of the binding portions 4, 6 of the bookscovers.

The sheet 14 may have openings 2l therethrough, between the sheaths, and radapted to receive, or permit'access to, the posts2 of the binder and the means for adjusting the binder to leaf bodies of different thickness.

Other means for adjusting the sheet 14 in desired position relatively to the Vsheath 12 may be adopted as desired.V

The invention being intended to be pointed out in the claims, is not to be limited to or by details of construction of the particuvlar embodiment thereof illustrated by the drawings or hereinbefore described.

I claim:

1. In a device ofthe character described; a pair of sheaths for the covers respectively of a book into which sheaths the outer. edges of said covers respectively are thrustable, one of the sheaths having an opening through its inner wall and the other sheath having a flexible sheet extending from its outer wallv and into the first mentioned Y sheath between its outer wall and the books cover'therein and having a strap portion eX- tending around the outer edge of said cover and through said opening.

2. In a device of the character described;

Y a pair of sheaths for the covers respectively openingy through its inner wall and the'v other sheath having a flexible'sheet extending from its outer wall and into the rst mentioned sheath between its outerrwall and the binders cover therein and having a Y strap portion extending around the outer edge of said cover and through said opentherethrough ,between the -sheaths and adapted to receive the post of saidbinder.

ing, the flexible sheet' having an opening 110 '3. In a device of the character described; a pair of sheaths Jfor the covers respectively of a book into which sheaths the outer edges of said coversrespectvely are thrustable,

one of the sheaths having a flexible sheet extending from its outer Wall and around the binding edge of the book and into the `other sheath between its outer Wall and the books cover therein; means for adjusting said sheet relatively to said second sheath. 10

v In testimony whereof I have hereunto set rny hand at Grand Rapids, Michigan, this` 18th day of January, 1921.
